Paul, Responding to your call for review, I took a look and generally I think it looks fine, but I do have a couple of comments/questions: ... 1. Introduction, and elsewhere: I assume this reference: draft-fielding-uri-rfc2396bis [2396bis] will be updated as this goes forward for publication? ... 2. Scheme Definition: [[ A FTP URL follows the standard syntax described in draft-fielding-uri-rfc2396bis [2396bis]. If :<port> is omitted, the port defaults to 21. ]] That's the command channel port, right? Does the FTP URI spec have anything to say about the data channel port? I guess not. ... 2.2 FTP url-path: [[ Historical note: Most FTP client implementations precede the <cwd1> with a "/" before sending the CWD command. This is arguably in conflict with RFC 1738, although the practice is quite widespread. Thus, a client that is presented with the URL <URL:ftp://myname@example.com/abc/def> might send the two commands "CWD /abc" and "RETR def" or it might send the two commands "CWD abc" and "RETR def". Server implementers should be aware of these two different interpretations of the same URL. ]] That looks like a potential security problem to me... shouldn't FTP servers avoid allowing accesses outside the indicated user's area (subtree)? I don't recall the details of how FTP works here, but is this topic worth a note under security considerations? ... #g At 18:19 28/10/04 -0700, Paul Hoffman / IMC wrote: >In a previous message, I said: > >>I updated the "ftp" draft to reflect the discussion on the list; it is >>now available as draft-hoffman-ftp-uri-02.txt.
